Most Commonly Tested Professional Responsibility Issues

The NCBE publishes a subject-matter outline for the MPRE with percentage ranges for each topic. Conflicts of interest is the single largest category, followed closely by the client-lawyer relationship and by litigation and other forms of advocacy. Confidentiality, competence and civil liability, regulation of the profession, and communications about legal services form the middle tier. Safekeeping property, transactions with non-clients, the lawyer's different roles, duties to the public, and judicial conduct are smaller but reliably present. Pull the current outline from ncbex.org before you start reviewing; the ranges shift slightly between administrations.

The tested law is the ABA Model Rules of Professional Conduct and the ABA Model Code of Judicial Conduct, plus constitutional decisions that limit what states may regulate. Your law school exam may differ. Some professors test their state's rules (California, New York, Texas, and Florida all deviate in tested ways), and many test malpractice, ineffective assistance under Strickland v. Washington, 466 U.S. 668 (1984), and the attorney-client privilege as evidence law. Ask your professor whether the Model Rules control.

Run a fixed sequence. First identify who the client is. Then ask: is this a current-client conflict (Rule 1.7), a former-client conflict (Rule 1.9), a specific transactional conflict (Rule 1.8), or a conflict imputed from another lawyer in the firm (Rule 1.10)? Rule 1.7 covers direct adversity and material limitation; Rule 1.9 requires the same or a substantially related matter plus materially adverse interests.

Then ask whether the conflict is waivable. Under Rule 1.7(b), waiver requires reasonable belief in competent and diligent representation, no law prohibiting it, no assertion of a claim by one client against another in the same litigation, and informed consent confirmed in writing. Suing your own current client on behalf of another client in the same proceeding is nonconsentable, period. Note the distinction the answer choices exploit: 'confirmed in writing' (most conflicts) versus 'signed by the client' (Rule 1.8(a) business transactions and Rule 1.8(g) aggregate settlements).

Rule 1.8 subsections are pure memorization and appear constantly. Business transactions with a client require fair terms in writing, written advice to seek independent counsel, and written signed consent. No substantial gifts drafted for yourself or close relatives. No literary or media rights before the matter concludes. No financial assistance except litigation costs (contingent on outcome for a paying client, outright for an indigent client) and modest gifts to pro bono clients. No sexual relationship unless it predates the representation, and that one is not imputed to the firm under Rule 1.8(k).

For imputation, know that Rule 1.10 permits screening of a lateral lawyer with prompt written notice to the affected former client. Rules 1.11 (former government lawyers), 1.12 (former judges, clerks, arbitrators), and 1.18 (prospective clients) each have their own screening provisions, and the language differs. A prospective client who consults you and hires no one still generates a confidentiality duty and a possible disqualification.

Separate Rule 1.6 from the attorney-client privilege on sight. Rule 1.6 covers all information relating to the representation, whatever the source, and is enforced by discipline. The privilege is an evidentiary rule covering confidential communications for the purpose of legal advice, invoked in response to compelled testimony. See Upjohn Co. v. United States, 449 U.S. 383 (1981), for the corporate scope of the privilege. Fact patterns that ask 'may the lawyer be compelled to testify' are privilege questions; 'is the lawyer subject to discipline' are Rule 1.6 questions.

Every exception in Rule 1.6(b) is permissive ('may reveal'), so any answer choice saying the lawyer 'must' disclose under 1.6(b) is wrong. Memorize all seven: preventing reasonably certain death or substantial bodily harm; preventing or mitigating substantial financial injury from a crime or fraud in which the client used the lawyer's services; securing legal advice about compliance; self-defense in a claim or proceeding; complying with other law or a court order; and detecting conflicts in a lateral move or merger. Rule 1.6(c) adds a competence-adjacent duty to make reasonable efforts to prevent inadvertent or unauthorized disclosure, which is where data-security questions live.

Rule 3.3 overrides Rule 1.6. If a client or witness has offered material evidence the lawyer comes to know is false, the lawyer must take reasonable remedial measures including, if necessary, disclosure to the tribunal, and this duty continues to the conclusion of the proceeding. Nix v. Whiteside, 475 U.S. 157 (1986), holds that refusing to assist perjury is not ineffective assistance. Contrast Rule 4.1(b), which requires disclosure to a third person only when necessary to avoid assisting a crime or fraud and only when disclosure is not prohibited by Rule 1.6.

Rule 1.13 is the organizational-client sleeper. The lawyer represents the entity; on knowledge of a violation likely to cause substantial injury, the lawyer must report up the chain to the highest authority, and may report out to the extent reasonably necessary if the highest authority fails to act. Note the Rule 1.13(f) warning to constituents when their interests conflict with the entity's.

Rule 1.5 forbids unreasonable fees and requires contingent fee agreements to be in a writing signed by the client, stating the method of calculation and whether expenses come off the top or the bottom. Contingent fees are prohibited in criminal defense and in domestic relations matters where the fee is contingent on securing a divorce or on the amount of alimony, support, or a property settlement. Fee division between lawyers in different firms requires proportional division or joint responsibility, client agreement confirmed in writing, and a reasonable total fee.

Rule 1.15 questions are formulaic. Client and third-party funds go in a separate trust account, never commingled with the lawyer's own money except funds to cover bank charges. The lawyer must keep records for five years after termination, promptly notify the client of receipt, promptly deliver funds the client is entitled to receive, and render an accounting on request. When ownership is disputed, the disputed portion stays in trust while the undisputed portion is distributed. Advance fees are client property until earned; a true retainer paid for availability may be treated as the lawyer's on receipt.

Rule 3.1 (meritorious claims), 3.3 (candor, including the duty to disclose directly adverse controlling authority not disclosed by opposing counsel), 3.4 (fairness: no obstructing access to evidence, no unlawful alteration or destruction, no paying occurrence witnesses contingent fees), 3.5 (no ex parte contact with judges or jurors), 3.6 (trial publicity and the substantial-likelihood-of-material-prejudice standard), and 3.7 (lawyer as necessary witness, which is generally not imputed to the firm) all appear regularly.

Rule 3.8 gives prosecutors extra duties: probable cause, timely disclosure of exculpatory and mitigating information, and the 2008 provisions on new evidence of innocence. Pair it with Brady v. Maryland, 373 U.S. 83 (1963), and remember the ethical disclosure duty is broader than the constitutional one because it has no materiality threshold.

Rule 4.2 forbids communication about the subject of the representation with a person known to be represented, absent consent of that person's counsel or authorization by law or court order. Rule 4.3 governs unrepresented persons: no legal advice other than to secure counsel, and correct any misunderstanding of your role. Rule 4.4(b) requires only notification to the sender of an inadvertently sent document; it does not require returning or refraining from reading it under the Model Rules.

Rule 7.1 is the master rule: no false or misleading communications about the lawyer or the lawyer's services. Rule 7.2 permits advertising through any media, permits paying the reasonable cost of advertising and the usual charges of a legal service plan or qualified lawyer referral service, and since the 2018 amendments permits nominal thank-you gifts for referrals. Specialty claims require certification by an approved organization plus naming it, with the standing exceptions for patent and admiralty practice.

Rule 7.3 bans live person-to-person solicitation for pecuniary gain unless the target is a lawyer, a family member, a close personal or prior professional contact, or someone who routinely uses that type of legal service. The constitutional overlay is worth knowing: Bates v. State Bar of Arizona, 433 U.S. 350 (1977) (truthful advertising is protected); Ohralik v. Ohio State Bar Ass'n, 436 U.S. 447 (1978) (in-person solicitation may be banned); In re Primus, 436 U.S. 412 (1978) (political and associational solicitation by a nonprofit is protected); Shapero v. Kentucky Bar Ass'n, 486 U.S. 466 (1988) (targeted direct mail is protected); Florida Bar v. Went For It, Inc., 515 U.S. 618 (1995) (a 30-day post-accident mail ban survives).

Rule 5.5 covers multijurisdictional practice: temporary services associated with local counsel, related to a pending or reasonably anticipated proceeding where you expect to be admitted pro hac vice, related to an arbitration arising out of practice in your home state, or otherwise reasonably related to your home-state practice. Rule 5.4 bars sharing legal fees with nonlawyers and nonlawyer ownership of law firms. This is genuinely jurisdiction-dependent now: Arizona has eliminated Rule 5.4 and licenses alternative business structures, Utah runs a regulatory sandbox, and D.C. has long allowed limited nonlawyer partnership. The MPRE tests the Model Rule.

Rule 8.3 requires reporting only when the lawyer knows of a violation raising a substantial question as to another lawyer's honesty, trustworthiness, or fitness. Information protected by Rule 1.6 is exempt, as is information learned while participating in an approved lawyers assistance program. Rule 8.4 defines misconduct, including 8.4(c) dishonesty and the newer 8.4(g) on harassment and discrimination in conduct related to the practice of law; note that several states have declined to adopt 8.4(g).

Rules 5.1, 5.2, and 5.3 govern supervision. Partners and managers must have measures in place; supervisors are responsible for a subordinate's violation if they order it, ratify it, or know of it in time to avoid or mitigate consequences and fail to act. A subordinate lawyer is protected only for acting on a supervisor's reasonable resolution of an arguable question of professional duty, which means the answer choice offering blanket 'just following orders' protection is wrong.

For judicial conduct, focus on Model Code Rule 2.11 disqualification (personal bias, personal knowledge of disputed facts, prior involvement as a lawyer, economic interest however small in the subject matter or a party), Rule 2.9 ex parte communications, Rule 3.7 charitable and fraternal activities, and the campaign restrictions. Two constitutional cases matter: Caperton v. A.T. Massey Coal Co., 556 U.S. 868 (2009) (extreme campaign spending can require recusal), and Republican Party of Minnesota v. White, 536 U.S. 765 (2002) (a judicial candidate cannot be barred from announcing views on disputed legal issues).

On the MPRE, read the call before the facts and note which standard it uses. 'Subject to discipline' means a Model Rules violation. 'Subject to civil liability' means malpractice or breach of fiduciary duty, which requires damages and causation and can exist without any rule violation. 'Subject to litigation sanction' means Rule 11 or a court's inherent power. 'Proper' usually means the conduct is permitted even if not required. The most common trap is a true statement that answers the wrong question.

Two more traps. First, 'may' versus 'must' decides more questions than anything else; almost every Rule 1.6(b) exception and the Rule 1.16(b) permissive withdrawal grounds are discretionary, while Rule 1.16(a) withdrawal, Rule 3.3 remediation, and Rule 8.3 reporting are mandatory. Second, the Model Rules abandoned 'appearance of impropriety' as a disciplinary standard for lawyers; an answer choice resting on appearances alone is usually wrong for lawyers, though appearance language survives in the Code of Judicial Conduct.

On a law school essay, organize by rule number, state the standard, apply the specific facts, and address the cure. Graders award points for identifying whether consent was available and what form it had to take, not for concluding that something 'looks unethical.' Practice with released NCBE questions rather than commercial ones where you can; the distractor style is distinctive and learnable.
